FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent N 0. 599,691, dated March1, 1898.

A ar -mot filed m 26, 1897. fierial No. eiaooo. (No model.)

, To an whom it may concern:

Be it known that I, HUGH II. DE FRANCE, a citizen of the United States,residing at Golden, in the county of Jefferson and State of Colorado,have invented certain new and useful Improvements in Fountain-Pens; and

' I do hereby declare the, following to be a full,

fountain-pens, and particularly to that class thereof in which theink-chamber of the pen is filled with ink by the actionof a pistonworking in the ink-chamber; and it consists in an improved fountain-penof this character provided with an attachment for'regulating the flow ofink to the pen the construction and arrangement of the parts of whichwill be hereinafter fully described, and particularly pointed out in theclaims.

The object of my invention is to provide fountain-pens in which theink-chamber is filled with ink by the action of a piston workthe case ofthe pen.

ing within the same, with an attachment for regulating the flow of inkto the pen, which will be simple in constructiomeasy to manipulate, andnot liable to get out of order.

In accomplishing the object of my invention I attach to the piston whichworks within the ink-chamber a piston-rod which is sufficiently long toextend outside of the case in which the ink-chamber is held at all timesduring the movement of the piston. Near the outer end of the piston-rodIattach a feedrod, which slides in a slot or groove formed in thepen-case. long to allow for the outward movement of the piston-rodWithout leaving the groove in which it is held. The groove in which itslides is formed on the thumb-hand side of the case, and the feed-rod isprovided with a thumb-piece by means of which it can be operated so asto force the piston inward and cause the feeding of ink to the pen. Thethumb-piece is preferably pivotally attached to the feed-rod, so that itwill turn down upon When in this position,

it serves as a clamp toprevent movement of the feed-rod, and thereforeof the piston, so that-improper feeding of ink to the pen is avoided.

The feed-rod is sufficiently My invention is fully illustrated in thedrawings which accompany and form a part of this specification, in whichthe same reference-letters refer to the same or corresponding parts, andin Which Figure l is a sectional view of my improved fountain-pen. Fig.2 is a detail view showing the piston, piston-rod, and feed-rod. Fig. 3is a detail view showing the pen-case and the groove cut therein, withinwhich the feedrod'slides. Fig. 4 is a view of some of the forms ofink-chambers which can be used in connection with my pen.

Referring to the drawings, Arepresents the ink-chamber ofi myfountain-pen, and B the case thereof. The feed end of the ink-chamher issomewhat conical in shape, as shown at a, and is formed with an openingat its apex a, through which ink flows upon the point of the pen 0. Thepen 0 is inserted in a groove 1), formed in the end of the case of thepen, and may be either gold or steel. Any ordinary form of pen may beused. By changing the form of the end of the ink-chamber according toone of the types shown in Fig. at the pen can be either inclined to orlie in the plane of the case.

Within the ink-chamber is the piston D. The piston D reciprocates withinthe inkchamber and serves when drawn backward to draw up ink within theink-chamber in the customary and well-known manner. To it is attachedthe piston-rod D, formed with a head or end D by means of which it canbe conveniently operated.

To the outer end of the piston-rod D is attached one end of the feed-rodE, which slides in the groove E, formed on the thumb side of thepen-case, and has attached thereto a thumb-piece E, by means of which itcan be convenientlyoperated. Thethumb-pieceE when the pen is being used,is at right an gles to the body of the pen. It maybe formed integrallywith the feed-rod or may be pivotally attached thereto. The latterconstruction is preferable, for it enables the thumbpiece to act as aclamp when bent down so as to lie flat with the pen-case, and thusprevent accidental movement of the feed-rod and piston. It is thisconstruction that is shown in the drawings. In the pen-case there isformed the aperture E in which the thumb= piece may be clasped down whenthe pen is not in use. Aband E passes around the pencase, near the rearend thereof, and serves not only to hold the feed-rod within the grooveprovided therefor, but to prevent the piston from being drawn out of thetube.

The operation of my pen is very simple. By unclasping the thumb-piece Eimmersing the point of the pen and tube in the ink, and drawing thepiston outward the tube or ink-chamber is filled with ink and is readyto write three or four pages. After that a slight drawing of the pistoninward, which is done by placing the thumb on the thumbpiece andpressing the same a short distance toward the pen-point, renews the flowof ink to the pen and three or four more pages can be written, and so ontill the reservoir is emptied.

The reservoir and pen can be thoroughly cleaned by immersing it in waterand operating it like a syringe.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a fountain-pen, the combination with a pen-case, an ink-reservoir,a piston and a piston-rod attached thereto, of a feed-rod attached tosaid piston-rod and extending down the side of the pen-case, and meansfor holding said feed-rod in a fixed position, whereby accidentaldischarge of ink is prevented, substantially as described.

2. In a fountain-pen, the combination with a pen-case having a groovecut therein on the thumb side thereof, an ink-chamber, a piston and apiston-rod attached thereto, of a feedrod attached to said piston-rodand guided within the groove in said pen-case, and a thumb-piecepivotally attached to the inner end of said feed-rod whereby when saidthumb-piece is turned down, it will clamp against the ink-reservoir andhold said feedrod in a fixed position, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

HUGH II. DE FRANCE.
